thenewcamera.com exclusive news – Canon EOS R Mark II To Feature Dual IS first published at thenewcamera.com website
We have spotted Canon fullframe mirrorless camera patents which clearly shows off Dual IS function which includes Sensor shift Image stabilization (IBIS) as well as lens based Image stabilization working together. The REAL Dual IS system will not only work in video it will also work in still mode. With the help of Lens based, Sensor based and Digital IS (Trio Combo) features users will be able to get hyper smooth video clips from the camera.
Patent is new and very Soon, but we strongly believe that Canon will implement in next generation of professional Mirrorless cameras including Canon EOS R Mark II.

Canon DUAL IS Mirrorless Camera Patent Details
Patent Text Translated from Japanese (Machine Translation)
Japanese Patent Laid-Open No. (“JP”) 2009-265182 discloses an imaging system that changes a ratio (correction ratio) between a correction amount by moving an image sensor on a camera side and a correction amount by moving the correction lens on an interchangeable lens side in accordance with an image stabilization amount. More specifically, the image is stabilized prior to imaging (exposure) by moving only the correction lens, and the image is stabilized during the imaging by moving both the correction lens and the image sensor. Then, the camera starts controlling the movement of the image sensor for the image stabilization after moving the image sensor in accordance with the position of the correction lens when the imaging starts.
IIS (InCamera Image Stabilization)
Thereby, the image is stabilized by moving the image sensor 104 (referred to as IIS hereinafter). The IIS is performed for the camera shake in the vertical direction (pitch direction) and the camera shake in the horizontal direction (yaw direction).

Finally Canon is going crazy with new FF Mirrorless lenses, Canon working on ultra-bright upto F1.0 wide-angle lens for their RF Mount. In general we have seen camera company generally takes 1 or 2 years of time to to convert a patent into a real product, so we have to wait for it.

Canon patent shows they are planning to add two sensors in once camera. And, its not a mirrorless they will keep the mirror inside the camera to reflect some portion of light to secondary sensor. The main intention of the entire setup to maximize the image quality.
Canon Patent Double Sensor in a camera
The half mirror 103 splits the imaging light beam (subject light beam) that has passed through the imaging optical system 102 into a first light beam and a second light beam. The first image sensor 104 and the second image sensor 105 receive the first light beam and the second light beam, respectively. The first image sensor 104 and the second image sensor 105 are constituted by a CCD image sensor, a CMOS image sensor, or the like. The first image sensor 104 and the second image sensor 105 have an image pickup pixel and a focus detection pixel for autofocus using a phase difference detection method. The MPU 106 includes a CPU and a memory that stores a program executed by the CPU, and functions as a control unit that controls the overall operation of the camera body 101. Further, the MPU 106 controls the driving of the photographing lens 102b via the lens driving motor 108.

According to a latest patent Canon is working on a eye-controlled autofocus for their upcoming Mirrorless camera. The EOS-3 was the first Canon camera to introduce eye-controlled autofocus back on November 1998.
How Eye Controlled AF Work
The camera features a infrared transmitter and receiver mounted around the eyepiece monitored the position of the iris, thus “knowing” where the photographer was looking and focusing on that point. At that time the system was having some system limitations however, notably eyeglasses and occasionally contact lenses would confuse the system.
New Eye AF Patent for Mirrorless Camera
Patent Details Machine translated
In addition, a display element 10 composed of a liquid crystal or the like for displaying a captured image, a display element driving circuit 11 for driving the display element 10, and an eyepiece 12 for observing a subject image displayed on the display element 10 are provided. Has been placed. Reference numerals 13a to 13b denote light sources for illuminating the photographer’s eyeball 14 for detecting the direction of the line of sight from the relationship between the elephant and the pupil reflected by the cornea reflection of the light source conventionally used in a single-lens reflex camera or the like. The infrared light emitting diode is disposed around the eyepiece 12. The illuminated eyeball image and the image by corneal reflection of the light sources 13a to 13b are transmitted through the eyepiece lens 12, reflected by the light splitter 15, and the eyeball lens in which the photoelectric element array of the CCD ridge is arranged two-dimensionally by the light receiving lens 16. An image is formed on the image sensor 17. The light receiving lens 16 positions the pupil of the photographer’s eyeball 14 and the image sensor 17 for the eyeball in a conjugate imaging relationship. The line-of-sight direction is detected by a predetermined algorithm, which will be described later, from the positional relationship between the eyeball imaged on the eyeball image sensor 17 and the corneal reflection of the light sources 13a to 13b.
So, Canon will be implementing Eye AF in their pro mirrorless camera in 2021-2022. In general once a patent gets registered it takes 2 to 3 years to become a real product.
